Geranium plant named ‘KLEPZ05141’

ABSTRACT

A new and distinct cultivar of Zonal  Geranium  plant named ‘KLEPZ05141’, characterized by its upright and rounded plant habit; freely branching habit; leaves with a distinct zonation pattern; freely flowering habit; semi-double bright red-colored flowers; and good garden performance.

Botanical designation: Pelargonium×hortorum.

Cultivar denomination: ‘KLEPZ05141’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Zonal Geranium, botanically known as Pelargonium×hortorum, and hereinafter referred to by the name ‘KLEPZ05141’.

The new Zonal Geranium is a product of a planned breeding program conducted by the Inventor in Stuttgart, Germany. The objective of the breeding program is to create new freely-branching and uniform Zonal Geranium cultivars with early flowering habit and attractive foliage and flower coloration.

The new Zonal Geranium originated from a cross-pollination made by the Inventor in Stuttgart, Germany in 2001 of a proprietary selection of Pelargonium×hortorum identified as code number F 012, not patented, as the female, or seed, parent with a proprietary selection of Pelargonium×hortorum identified as code number ZL 471, not patented, as the male, or pollen, parent. The cultivar KLEPZ05141 was discovered and selected by the Inventors as a single flowering plant from within the progeny of the stated cross-pollination in a controlled environment in Stuttgart, Germany in June, 2002.

Asexual reproduction of the new Zonal Geranium by vegetative terminal cuttings in a controlled environment in Stuttgart, Germany since 2002, has shown that the unique features of this new Zonal Geranium are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar KLEPZ05141 has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘KLEPZ05141’. These characteristics in combination distinguish ‘KLEPZ05141’ as a new and distinct cultivar of Zonal Geranium:

-   -   1. Upright and rounded plant habit.     -   2. Freely branching habit.     -   3. Leaves with a distinct zonation pattern.     -   4. Freely flowering habit.     -   5. Semi-double bright red-colored flowers.     -   6. Good garden performance.

Plants of the new Zonal Geranium differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Leaves of plants of the new Geranium have a distinct zonation         pattern whereas leaves of plants of the female parent selection         do not have a distinct zonation pattern.     -   2. Plants of the new Geranium and the female parent selection         differ in flower color as plants of the female parent selection         have dark red-colored flowers.

Plants of the new Zonal Geranium differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Geranium are less vigorous than plants of         the male parent selection.     -   2. Plants of the new Geranium and the male parent selection         differ in flower color as plants of the male parent selection         have light red-colored flowers.

Plants of the new Zonal Geranium can be compared to plants of the Pelargonium×hortorum cultivar ‘Klesatha’, disclosed in U.S. Plant patent application Ser. No. 09/250,007 now abandoned. In side-by-side comparisons conducted in Stuttgart, Germany, plants of the new Zonal Geranium differed from plants of the cultivar Klesatha in the following characteristics:

-   -   1. Plants of the new Zonal Geranium were less compact than         plants of the cultivar Klesatha.     -   2. Leaves of plants of the new Zonal Geranium had a distinct         zonation pattern whereas leaves of plants of the cultivar         Klesatha did not have a distinct zonation pattern.     -   3. Plants of the new Zonal Geranium and the cultivar Klesatha         differed in flower color as plants of the cultivar Klesatha had         darker red-colored flowers.

Plants of the new Zonal Geranium can also be compared to plants of the Pelargonium×hortorum cultivar Kledap, disclosed in U.S. Plant Pat. No. 7,016. In side-by-side comparisons conducted in Stuttgart, Germany, plants of the new Zonal Geranium differed from plants of the cultivar Kledap in the following characteristics:

-   -   1. Plants of the new Zonal Geranium were less vigorous than         plants of the cultivar Kledap.     -   2. Plants of the new Zonal Geranium and the cultivar Kledap         differed in flower color as plants of the cultivar Kledap had         orange red-colored flowers.     -   3. Plants of the new Geranium had better garden performance than         plants of the cultivar Kledap.

DETAILED BOTANICAL DESCRIPTION

The photographs and following observations, measurements and values describe plants grown in Stuttgart, Germany in a glass-covered greenhouse during the summer and autumn and under conditions which closely approximate commercial Geranium production. During the production of the plants, day temperatures ranged from 18° C. to 22° C., night temperatures ranged from 14° C. to 18° C. and light levels ranged from 20,000 lux to 55,000 lux. Plants were about 2.5 months old when the photograph and the description were taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
